I've had a look at current X11 CVS drivers/nv, and it looks as if some
DMA acrobatics can now be performed by nv_video.c, but the brute of
the work (packing the YV12) apparently still happens on the host CPU
using NVCopyData420().

The DMA blits are - apparently - mainly used for VSync synchronization.

Is there a different driver than the one I'm looking at?

Thanks!


So long,
